Salinity stress has a great impact on crop growth and productivity and is one of the major factors responsible for crop yield losses. The K-homologous (KH) family proteins play vital roles in regulating plant development and responding to abiotic stress in plants. However, the systematic characterization of the family in rice is still lacking.
View Article and Find Full Text PDFSunflower ( L.) is an important, substantial global oil crop with robust resilience to drought and salt stresses. The TGA (TGACG motif-binding factor) transcription factors, belonging to the basic region leucine zipper (bZIP) family, have been implicated in orchestrating multiple biological processes.

- The study identifies a class of genes known as UBiA in sunflowers, which are involved in crucial processes like growth and the production of secondary metabolites, including chlorophyll and vitamin E.
- Researchers discovered 10 UBiA genes with conserved domains spread across six chromosomes, and through phylogenetic analysis, they classified 119 genes from 12 different species into five major groups with specific motifs.
- The expression of two key UBiA genes, HaUBiA1 and HaUBiA5, was notably influenced by various abiotic stresses, with HaUBiA1 upregulating under stress conditions while HaUBiA5 showed a decrease, suggesting their potential roles in stress response mechanisms for sunflowers.
Article Synopsis
- The study identifies 120 members of the family in plants, categorized into four subfamilies based on phylogenetic analysis.
- It reveals that each gene contains at least one AP2 domain and shows varied motif distributions, with significant cis-elements linked to hormone signaling and stress responses.
- The research highlights the role of a specific gene in drought stress, showing it interacts with DREB2A and inhibits an enzyme's expression in response to ABA, providing insights into the gene's biological function in stress response.
